[Rd] Could .Primitive("[") stop forcing R_Visible = TRUE?

[Duncan Murdoch]

My message below sounds a little aggressive, I apologize in advance for 
that.  But I can't think of better wording.

This is a small change, which will have a small benefit, mainly for the 
data.table authors, who really brought it on themselves by choosing to 
(ab)use R extraction syntax to have side effects.  Surely you or they 
should be the ones to run the test across all of CRAN?
